Google Drive Sync
Stealth Browse can sync your saved passwords and payment methods to your own Google Drive, and upload encrypted full backups. Drive is used purely as a storage layer - everything is stored under the app's own scoped drive.file permission so Stealth never sees other Drive content.
What syncs
| Passwords | stealth-browse-passwords.json |
| Payment methods | stealth-browse-payments.json |
| Full backup | stealth_backup_<timestamp>.stealthbackup (encrypted) |
Connecting
- Open Settings → Sync (or the Google Sync entry from settings).
- Tap Sign in with Google and pick your account.
- Grant the
drive.filescope - this only allows Stealth to read/write its own files. - Toggle which categories to sync (Passwords, Payment Methods).
Sync Options
| Sync Now | Manually upload the latest passwords/payment data. |
| Auto sync interval | Hourly, Daily, Weekly, Monthly, or On change. |
| Last sync timestamp | Per-category (passwords, payments) saved locally. |
| Disconnect | Sign out and clear local Drive credentials. |
Encrypted Full Backup
From Settings → Data & Storage → Google Drive Backup you can upload a complete encrypted backup blob (passwords, payment methods, bookmarks, history, plugins, settings) to Drive. The file is AES-encrypted before upload - Google never sees plaintext.
Sign-in Issues
- Error 10 (developer error): Reported when the app's signing certificate doesn't match what Google has on file. Reinstall using the official APK from Stealth.
- "Account already in use": Sign out from the existing account first.
- Network errors: Drive requires direct internet - if Tor is active, the sync request will fail. Sync without Tor enabled.
